The stepper motor module is used to control up to 2 stepper motors with a nominal voltage of 24 to 38.5 VDC ±25% at a motor current up to 3 A (5 A peak).

In addition, this module has 6 digital inputs that can be used as limit switches or encoder inputs.

Due to the individual adjustment of the coil currents, the motor is only operated with the current it actually needs. This simplifies the selection of the available motors and prevents unnecessary heating. Because this affects energy consumption and thermal load, the effects are positive on the service life of the complete system. Complete flexibility is achieved through the use of independently adjustable holding, boost and nominal current values. The current for microsteps is automatically adjusted to the configured current values.

The automatic motor identification system is an enormous help during standstills. The stepper motor modules can identify the connected motors using their coil characteristics and generate feedback in the form of an analog value. This makes it possible to detect not only wiring errors, but also incorrect motor types being used mistakenly. A stall detection mechanism is integrated to analyze the motor load. Detection of the stall is defined via a configurable threshold. This allows an overload or motor standstill to be detected precisely in many different types of applications.
